Ethyl 1-sec-butyl-2-(4-methoxyphenyl)-1H-benzimidazole-5-carboxylate
Abstract
In the title molecule, C21H24N2O3, the dihedral angle between the benzene and imidazole rings is 66.33 (13)°. The imidazole ring is essentially planar, with a maximum deviation of 0.004 (2) Å. In the crystal structure, molecules are connected by weak C—H...O hydrogen bonds, forming chains along the b axis
